Abstract
Extensive research has been done in the past ten years on the energy harvesting, which enables many promising applications like self-powered wireless sensors. The energy harvesting is also being extended to large energy scale. In this seminar the speaker will overview the energy harvesting at micro and milli watts scale, then present his unique efforts and recent results on large scale energy harvesting, with interdisciplinary challenges in intelligent materials, vibration dynamics, mechatronics design, control systems, and power electronics. The topics include energy-harvesting tuned mass damper for tall buildings, energy-harvesting vehicle suspensions, mechanical motion rectifier-based power takeoff for ocean wave energy harvesting and railway track energy harvesting. Vibration energy harvesting based on piezoelectric materials will also be presented in which we stress on the strategies of increasing the harvesting power and achieving simultaneous vibration control. Finally the speaker will summarize his vision of energy harvesting research.
